Code Description

ICD-10 N83.521 is a billable code used to indicate a diagnosis of torsion of right fallopian tube.

Key Diagnostic Point:

Torsion of the fallopian tube is a condition where the tube twists around itself, compromising its blood supply. This condition can lead to ischemia and necrosis if not promptly diagnosed and treated. Torsion of the right fallopian tube specifically refers to this occurrence on the right side. Symptoms often include acute abdominal pain, nausea, and vomiting, which can mimic other conditions such as ovarian cyst rupture or ectopic pregnancy. Diagnosis typically involves imaging studies, such as ultrasound, to assess blood flow and the presence of any associated masses. Treatment usually requires surgical intervention to untwist the tube and restore blood flow, and in some cases, removal of the affected tube may be necessary. The condition can be associated with other gynecological disorders, including endometriosis, which may predispose individuals to torsion due to adhesions or abnormal anatomical positioning. Understanding the clinical implications and potential complications of torsion is crucial for effective management and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between torsion and other acute abdominal conditions.
  • Need for imaging studies to confirm diagnosis.
  • Potential for associated conditions like endometriosis or ovarian cysts.
  • Variability in presentation and symptoms among patients.

Audit Risk Factors

  • Inadequate documentation of symptoms leading to diagnosis.
  • Failure to document imaging studies performed.
  • Lack of clarity on surgical interventions performed.
  • Misclassification of the condition as a different gynecological issue.
